Q

causes of edema

A

a. Increased permeability of the capillaries. The capillaries are allowing too much fluid in and not enough out. The cells are swelling.b. Increased capillary pressure due to venous obstruction or heart failure.c. Inflammatory conditions - due to injury.d. Fluid / electrolyte problems – post surgical problems

31
Q

a thrombi becoming mural (or changing location) is the greatest risk because?

A

the attached blood clot has become infected, and once it becomes infected, it will spread

32
Q

consequences of thrombi depend on what?

A

where it is located

33
Q

a consequence of thrombosisthrombosis present in the artery – causes reduction in arterial blood supply. Restricts blood flow

A

ischemia

34
Q

the most common consequence of thrombosis. Present in the vein.

A

Passive hyperemia

35
Q

a consequence of thrombosisdeath of the tissue caused by interference in blood supply - ischemic necrosis + putrefaction

A

gangrene
